PCB012 Power Distribution Board Self-Adapt Distributor HO N O LED Street Light Hub DC AC Voltage Train Power Control

You can select any type for power input, 4V to 24V, AC or DC. There is no limit on the input current because an output current controller can adapt the output current. It features dimmer control for LED lights and can adjust light brightness (clockwise = brighter).
Output Voltage Controller: Controller at 3V, output is stable 3V; Controller at DIR, output is near to the input; Controller at 12V, output is stable 12V. One distributor can support up to 28 lights. It is easy to expand to several boards if you need to use more lights. Please use lights that need the same current and voltage on one distributor. Do not mix lights with different operating current and voltage on the same distributor. You can prepare another Power Distribution Board to use as the expanding one. The total output current must be less than the input current. For example, normally one LED light needs 20mA; one 1000mA transformer can support 50 such LED lights in total, but it will only support 10 pieces of 100mA bulb lights
